BACKGROUND

1. Field of the Invention

The present inventions relate to child seats provided with anchoring harnesses.

2. Description of the Related Art

Conventionally, an automobile vehicle has seatbelts provided at the front and rear seats. The seatbelt generally includes shoulder and lap straps that may be fastened with an anchor point of the vehicle to restrain and protect the occupant in case of collision or sudden stop of the vehicle. However, the use of the vehicle seatbelt is not adapted for a young child who has a smaller body and may not be able to sustain the pressure applied by the seatbelt. As a result, safety legislations require the use of a child safety seat for seating a young child in a vehicle. The seatbelt of the vehicle can be used to hold the child safety seat in place, whereas the child safety seat has an internal child restraint harness more adapted to provide protection for the young child.

For a child of higher age, the size of the child safety seat may not be adapted to seat the child having a larger body. In this case, a booster seat may be used to increase the height at which the child sits, and the seatbelt of the vehicle can be used to properly restrain the child. Unlike the child safety seat, the booster seat is usually placed on the vehicle passenger's seat without attachment. When collision occurs, the booster seat may be subject to displacement, which may adversely affect the restraining protection provided by the seatbelt.

Accordingly, there is a need for a child seat that can be securely held in place when installed in a vehicle, and address at least the foregoing issues.

SUMMARY

The present application describes child seats having anchoring harnesses that can attach with an external anchorage fixture, such as the anchorage fixture provided in a vehicle. In some embodiments, the child seat includes a seat portion and an anchoring harness. The seat portion has a lower surface facing downward, an upper surface facing upward for providing sitting support, a rear edge connecting with the lower and upper surfaces and defining a rear border of the lower and upper surfaces, and a slot formed through the seat portion and opened on the lower and upper surfaces, the slot being located adjacent to the rear edge. The anchoring harness is routed through the slot and extends outward on the lower surface and the upper surface. The anchoring harness includes a first and a second end opposite to each other, the first end being provided with a fastener operable to attach with an external anchorage fixture for holding the child seat in place, and the second end being positioned across the slot adjacent to either of the upper surface and the lower surface, the second end being in contact against a region of the seat portion around the slot to retain the anchoring harness with the seat portion.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present application describes child seats having anchoring harnesses. Embodiments of the child seat include a seat portion and an anchoring harness. The seat portion has an upper surface and a rear edge, and an armrest protruding from the upper surface. The anchoring harness can be attached with the seat portion at a location near the rear edge of the seat portion and the armrest. The anchoring harness can include a strap that is attached with the seat portion at one end, and is provided with a fastener at an opposite distant end. When the child seat is placed on a vehicle passenger's seat, the fastener can attach with an anchorage fixture of the vehicle, whereby the anchoring harness can hold the child seat in place.

FIG. 1A is a perspective view illustrating an embodiment of a child seat 1. The child seat 1 has no backrest, and can be used as a booster seat. The child seat 1 can include a seat portion 12′, two armrests 14′ and an anchoring harness 16′. The seat portion 12′ can be formed from a seat shell, and can have an upper surface 12A on which a child can sit, and a lower surface 12B opposite to the upper surface 12A that can rest in contact on a support surface (e.g., the upper support surface of a vehicle passenger's seat). The seat portion 12′ can also have a rear edge 12C and left and right outer side surfaces 12L and 12R that define at least partially the outer side contour of the seat portion 12′. The rear edge 12C can correspond to a back side of a child, and can define a rear border of the upper surface 12A and the lower surface 12B. The left and right outer side surfaces 12L and 12R can be respectively flanked at the left and right sides of the upper surface 12A. The seat portion 12′ may be formed in a single body, and the lower surface 12B may form a substantially planar bottom surface for facilitating resting of the child seat 1 on a support surface.

As shown in FIG. 1A, the seat portion 12′ can also be provided with two slots 18′ that may be transversally spaced apart from each other in a region between the armrests 14′ and adjacent to the rear edge 12C. A material portion 12F of the seat portion 12′ can be interposed between the two slots 18′. Each of the slots 18′ can extend substantially vertically through the seat portion 12′, and respectively open on the upper surface 12A and the lower surface 12B. Moreover, each slot 18′ can have a bar segment 19′ that extends transversally adjacent to the slot 18′. The two slots 18′ and bar segments 19′ can be respectively located adjacent to the armrests 14′, and are exposed outward and accessible from an outside of the seat portion 12′.

The armrests 14′ can protrude upward from the upper surface 12A adjacent to the left and right outer side surfaces 12L and 12R, and extend to near the rear edge 12C. In some embodiments, the armrests 14′ may be formed integral with the seat portion 12′. In other embodiments, the armrests 14′ may be detachably assembled with the seat portion 12′.

FIG. 1B is an enlarged view illustrating the assembly of the anchoring harness 16′ with the seat portion 12′. The anchoring harness 16′ can be secured with the seat portion 12′ near the rear edge 12C and at least one armrest 14′ by wrapping around the bar segment 19′. The anchoring harness 16′ can include a fastener 162′ and a strap 164′. In some embodiments, the fastener 162′ may be formed with a hook shape adapted to attach with an external anchorage fixture (e.g., ring fixture) provided in the vehicle. In other embodiments, the fastener 162′ may take any forms adapted to engage with the anchorage fixture.

The strap 164′ can be made of a webbing material having a first end connected with the fastener 162′, and a second end that forms a loop 166′. The anchoring harness 16′ can be detachably assembled with the seat portion 12′ by routing the strap 164′ substantially vertically through one slot 18′ and wrapping the loop 166′ around the bar segment 19′. The end of the strap 164′ provided with the fastener 162′ then can be stretched rearward through the loop 166′ to tie the strap 164′ with the bar segment 19′. Accordingly, the strap 164′ can be secured with the seat portion 12′ at one end, and the fastener 162′ at the opposite end can be attached with an anchorage fixture (e.g., a ring fixture) provided in the vehicle for holding the child seat 1 on the vehicle passenger's seat.

According to the design needs, the anchoring harness 16′ can include two similar assemblies of the same fasteners 162′ and straps 164′ connected with the seat portion 12′, the loop 166′ of each strap 164′ being secured around one corresponding bar segment 19′.

FIG. 2A is a perspective view illustrating another variant embodiment of a child seat 2. The child seat 2 can include a seat portion 22, two armrests 24, and an anchoring harness 26 that can detachably assemble with the seat portion 22. Like previously described, the seat portion 22 can have an upper and a lower surface 22A and 22B, a rear edge 22C, and left and right outer side surfaces 22L and 22R. The seat portion 22 can have two slots 28 and bar segments 29 that are arranged adjacent to the rear edge 22C and are spaced apart from each other by a material portion 22F of the seat portion 22. The seat portion 22, the armrests 24, the slots 28 and the bar segments 29 may be similar to the embodiment described previously.

FIG. 2B is an enlarged view illustrating the assembly of the anchoring harness 26 with the seat portion 22. The anchoring harness 26 can be secured with the seat portion 22 at the rear edge 22C by wrapping around the bar segment 29. The anchoring harness 26 can include a fastener 262, and a strap comprised of a first strap portion 264 and a second strap portion 266. The first strap portion 264 can be made of a resilient material that can elastically deform (i.e., stretch and retract) so as to operate as a length adjustment part for facilitating adjustment of the length of the anchoring harness 26 between the fastener 262 and the rear edge 22C of the seat portion 22. The first strap portion 264 can have a first end connected with the fastener 262, and a second end provided with a connector 268 (e.g., button).

The second strap portion 266 can be made of a webbing material, and can have a first end that forms a loop 261 and a second end having a plurality of connectors 263 (e.g., slotted connectors) with any of which the connector 268 of the first strap portion 264 can detachably engage to attach the first strap portion 264 with the second strap portion 266.

It is worth noting the arrangement of the connectors 263 and 268 can be interchanged on the first and second strap portions 264 and 266 (e.g., the connectors 263 can be placed on the first strap portion 264, and the connector 268 on the second strap portion 266). Moreover, more or less of the connectors 263 can be provided according to the actual design needs.

For installing the anchoring harness 26 with the seat portion 22, the loop 261 of the second strap portion 266 can be wrapped around one bar segment 29, whereby the second strap portion 266 is securely retained with the seat portion 22. The connector 268 can be selectively engaged with any of the connectors 263 to attach the first strap portion 264 with the second strap portion 266 at a desirable length.

When the child seat 2 is installed on a vehicle passenger's seat, the first strap portion 264 can be stretched rearward of the seat portion 22, and the fastener 262 can be attached with the anchorage fixture provided in the vehicle. The child seat 2 can be thereby securely held on the vehicle passenger's seat.

When the child seat 2 is to be removed, the fastener 262 can be detached from the anchorage fixture of the vehicle. In alternate embodiments, the connector 268 can be disengaged from the connector 263 to detach the first strap portion 264 from the second strap portion 266. After removal of the child seat 2, the first strap portion 264 can remain attached with the anchorage fixture of the vehicle, whereas the second strap portion 266 remains attached with the seat portion 22.

According to the design needs, the anchoring harness 26 can include two similar assemblies of the fastener 262 and strap portions 264 and 266 attached with the seat portion 12, the loop 261 of each second strap portion 266 being secured around one corresponding bar segment 29.

The seat portion 32, the armrests 34, the slots 38 and bar segments 39 can be similar to the embodiments described previously.

FIG. 3B is an enlarged view illustrating the assembly of the anchoring harness 36 with the seat portion 32. The anchoring harness 36 can be secured with the seat portion 32 near the rear edge 32C by wrapping at least partially around the bar segment 39. The anchoring harness 36 can include a fastener 362, and a strap comprised of a first strap portion 364 and a second strap portion 366. The first strap portion 364 can be made of a resilient material that can elastically deform (i.e., stretch and retract) to operate as a length adjustment element 364A for facilitating adjustment of the length of the anchoring harness 36. The first strap portion 364 can have a first end connected with the fastener 362, and a second end connected with the second strap portion 366. An end of the second strap portion 366 opposite to that connected with the first strap portion 364 can form a loop 368 that is assembled with a stop ring 361.

For installing the anchoring harness 36 with the seat portion 32, the stop ring 361 and the second strap portion 366 can be routed substantially vertically through one slot 38 from the underside of the seat portion 32, and the stop ring 361 can be disposed so that it lies across the slot 38 from the upper side. When the anchoring harness 46 is pulled rearward, the ring 361 can rest in contact against a top of one bar segment 39 and/or the upper surface 32A of the seat portion 32 surrounding the slot 38 to retain the anchoring harness 46 with the seat portion 32.

In some variant embodiments, the stop ring 361 and the second strap portion 366 may also be routed substantially vertically through one slot 38 from the upper side of the seat portion 32, and the stop ring 361 can be disposed so that it lies across the slot 38 from the underside. This installation can also secure the anchoring harness 46 with the seat portion 32.

When the child seat 3 is installed on a vehicle passenger's seat, the first strap portion 364 can be stretched rearward of the seat portion 32, so that the fastener 362 can be attached with the anchorage fixture provided in the vehicle.

When the child seat 3 is to be removed, the ring 361 can be turned substantially vertically relative to the slot 38, and the second strap portion 366 can be pulled such that the ring 361 can be removed from the upper side of the slot 38. After removal of the seat portion 32 from the vehicle passenger's seat, the anchoring harness 36 can be left attached with the anchorage fixture of the vehicle and detached from the seat portion 32.

According to the design needs, the anchoring harness 36 can include two similar assemblies of the fastener 362 and strap portions 364 and 366 attached with the bar segments 39 of the seat portion 32.

The child seat 4 can include a seat portion 42, two armrests 44, and an anchoring harness 46 that can be detachably assembled with a rear of the seat portion 42. Like previously described, the seat portion 42 can have an upper and a lower surface 42A and 42B, a rear edge 42C, and left and right outer side surfaces 42L and 42R. The seat portion 42 can have two slots 48 and bar segments 49 that are arranged adjacent to the rear edge 42C and are spaced apart from each other by a material portion 42F of the seat portion 42. The seat portion 42, the armrests 44, the slots 48 and the bar segments 49 may be similar to the embodiments described previously.

FIG. 4B is an enlarged view illustrating the assembly of the anchoring harness 46 with the seat portion 42. The anchoring harness 46 can be secured with the seat portion 42 adjacently to the rear edge 42C by wrapping at least partially around the bar segment 49. The anchoring harness 46 can include a fastener 462, and a strap comprised of a first strap portion 464 and a second strap portion 466. The first strap portion 464 can be made of a resilient material that can elastically deform (i.e., stretch and retract) for modifying the length of the anchoring harness 46, thereby facilitating the attachment of the anchoring harness 46 and providing some degree of cushioning effect. The first strap portion 464 can have a first end connected with the fastener 462, and a second end connected with the second strap portion 466.

The second strap portion 466 can be made of a material different from the first strap portion 464, e.g., webbing material. An end of the second strap portion 466 opposite to that connected with the first strap portion 464 can be folded over itself and sewed together to form an abuttal part 466A having an enlarged shape. An intermediate region 466B of the second strap portion 466 can be defined between the abuttal part 466A and the first strap portion 464.

For installing the anchoring harness 46 with the seat portion 42, the abuttal part 466A and the second strap portion 466 can be inserted substantially vertically through one slot 48 from the underside of the seat portion 42, and the enlarged shape of the abuttal part 466A can be placed so that it lies across the slot 48 from the upper side. When the anchoring harness 46 is stretched rearward, the abuttal part 466A can rest in contact against a top of one bar segment 49 and/or the upper surface 42A of the seat portion 42 surrounding the slot 48. The anchoring harness 46 can be thereby securely retained with the seat portion 42.

When the child seat 4 is installed on a vehicle passenger's seat, the first strap portion 464 can be stretched rearward of the seat portion 42, and the fastener 462 can be attached with the anchorage fixture provided in the vehicle.

When the child seat 4 is to be removed, the abuttal part 466A can be turned substantially vertically relative to the slot 48, and the second strap portion 466 can be pulled downward such that abuttal part 466A disengages from the upper side of the slot 48. After removal of the seat portion 42 from the vehicle passenger's seat, the anchoring harness 46 can remain attached with the anchorage fixture of the vehicle and detached from the seat portion 42.

According to the design needs, the anchoring harness 46 can include two similar assemblies of the fastener 462 and strap portions 464 and 466 attached with the bar segments 49 of the seat portion 42.

The seat portion 52 can have two slots 58 and bar segments 59 that are arranged adjacent to the rear edge 52C and are spaced apart from each other by a material portion 52F of the seat portion 52. The seat portion 52, the armrests 54, the slots 58 and the bar segments 59 may be similar to the embodiments described previously.

FIG. 5B is an enlarged view illustrating the assembly of the anchoring harness 56 with the seat portion 52. The anchoring harness 56 can be secured with the seat portion 52 adjacently to the rear edge 52C by wrapping around the bar segment 59. The anchoring harness 56 can include a fastener 562, a strap 564 and a three-bar adjustment buckle 566. The strap 564 can be formed from a webbing material having a first end connected with the fastener 562, and a second end that is folded and sewed to form a looped tab 568. The strap 564 can pass substantially vertically through one slot 58 and wrap around the bar segment 59, and then be routed through the adjustment buckle 566. The adjustment buckle 56 can be operable as a length adjustment device for desirably adjusting a length of the strap 564 between the fastener 562 and the rear edge 52C of the seat portion 52.

When the child seat 5 is installed on a vehicle passenger's seat, the fastener 562 can be attached with the anchorage fixture of the vehicle to hold the child seat 11 in place. Owing to the friction contact between the strap 564 and the adjustment buckle 566, the strap 564 cannot easily slide relative to the adjustment buckle 566. When the position of the child seat 5 on the vehicle passenger's seat needs adjustment, the adjustment buckle 566 can be movably displaced relative to the strap 564 so as to adjust the length of the strap 564 between the seat portion 52 and the anchorage fixture of the vehicle.

FIG. 6A is a schematic view illustrating another variant embodiment of a child seat 6. The child seat 6 can include a seat portion 62, two armrests 64, and an anchoring harness 66 assembled with the seat portion 62. Like previously described, the seat portion 62 can have an upper and a lower surface 62A and 62B, a rear edge 62C, and left and right outer side surfaces 62L and 62R. The seat portion 62 can have two slots 68 and bar segments 69 that are arranged adjacent to the rear edge 62C and are spaced apart from each other by a material portion 62F of the seat portion 62. The seat portion 62, the armrests 64, the slots 68 and the bar segments 69 may be similar in construction to the embodiments described previously.

FIG. 6B is an enlarged view illustrating the assembly of the anchoring harness 66 with the seat portion 62.

The strap 668 also includes an intermediate portion that is routed substantially vertically through one slot 68 and wraps around the bar segment 69, and then is routed through the mount frame 662 between the fastener 666 and the clamping part 664. The length adjustment device comprised of the mount frame 662 and the clamping part 664 can be operable to hold and adjust the strap 668, and the looped tab 672 can prevent the strap 668 from entirely disengaging from the mount frame 662 and the clamping part 664.

FIGS. 6C and 6D are schematic side views respectively illustrating a locked and a release state of the anchoring harness 66. When the child seat 6 is installed on a vehicle passenger's seat, the fastener 666 can be attached with the anchorage fixture of the vehicle. The clamping part 664 can be operable so that the teeth 670 press and clamp a portion of the strap 668 against a surface of the fastener 666, as shown in FIG. 6C. The length of the strap 668 extending between the bar segment 69 and the fastener 666 can be thereby fixed, and the anchoring harness 66 can hold the child seat 6 in place.

Referring to FIG. 6D, for adjusting the length of the strap 668 between the fastener 666 and the rear edge 62C of the seat portion 62, the clamping part 664 can be pivoted relative to the mount frame 662 to cause the teeth 670 to disengage from the strap 668. Then the loop 672 or fastener 666 can be pulled to cause the strap 668 to slide through the mount frame 662. Once a desired length of the strap 668 is reached, the clamping part 664 can reversely rotate to clamp the strap 668.

FIG. 7A is a perspective view illustrating another variant embodiment of a child seat 7.

The seat portion 72 can have two slots 78 and bar segments 79 that are arranged adjacent to the rear edge 72C and are spaced apart from each other by a material portion 72F of the seat portion 72. The seat portion 72, the armrests 74, the slots 78 and the bar segments 79 may be similar in construction to the embodiments described previously.

FIG. 7B is an enlarged view illustrating the assembly of the anchoring harness 76 with the seat portion 72. The anchoring harness 76 can be secured with the seat portion 72 adjacently to the rear edge 72C by wrapping around the bar segment 79. The anchoring harness 76 can include a strap 762, a fastener 764, and a clipping device 766. The strap 762 can include a first end connected with the fastener 764, and a second end forming a looped tab 768.

FIG. 7C is a schematic view illustrating the clipping device 766. The clipping device 766 can include a clamping plate 770, a base 772, and a pivot shaft 774 through which the clamping plate 770 is pivotally assembled with the base 772. A gap 775 can be formed between the clamping plate 770 and the pivot shaft 774, and another gap 776 can be defined between the base 772 and the pivot shaft 774. An outer surface of the pivot shaft 774 can include a plurality of teeth 777 facing the base 772. The strap 762 can be routed substantially vertically through one slot 78, and then wrap around one adjacent bar segment 79 to form two parallel and overlapping strap segments A and B that are routed through the gaps 775 and 776 defined between the base 772, the pivot shaft 774 and the clamping plate 770. The fastener 764 and the loop 768 can be thereby located at a same side of the clipping device 766 opposite to the side of the bar segment 79. The clipping device 766 can be configured as a length adjustment device for adjusting a length at which the fastener 764 extends rearward distant from the rear of the seat portion 72, the looped tab 768 preventing the strap 762 from sliding out of the clipping device 766.

FIGS. 7D and 7E are schematic views respectively illustrating the clipping device 766 in clamping and unclamping states. In FIG. 7D, the clipping device 766 is shown clamping the strap 762.
